The following is a first installment (or rather I shall complete the present post piecemeal). My main sources have been: Indonesian: Dictionnaire indonésien-français (P. Labrousse), KBBI online; Thai: Thai English German Dictionary (J. Rohrer), Longdo online; Urdu: Oxford Urdu-English Dictionary. Entries are classed by alphabetical order of Indonesian words.

IN amerta (tidak dapat mati, abadi; tidak terlupakan) immortal; unforgettable
TH อมตะ (amata): 1 (ไม่ตาย) immortal, everlasting 2 (นิพพาน) nirvana — อมฤต (น้ำทิพย์) (amrit): elixir; nirvana
UR امرت (amrit): nectar conferring immortality, water or elixir of life — امرت دھارا (amrit dhara): “amrit shower” or “amrit channel,” herbal cure-all of Ayurvedic medicine
All these words are one and the same, deriving from Sanskrit अमृत amrita. — See the name of the Sikh holy city in Punjab, Amritsar, “amrit pond”. — Another Urdu word for a cure-all elixir is اکسیر (iksir), from the Arabic word that has given “elixir” (al-iksir), and which designates also the philosophers’ stone.

Bandar Seri Begawan is the capital city of the Sultanate of Brunei Darussalam. The sultans of Brunei formerly used the title Begawan, or Seri Begawan (see seri). Bandar is of Arabic origin (بندر), and means harbor.

IN buta: giant (mythical monster)
TH ภูต (put): ghost, demon
UR بھوت (bhut): 1 ghost, evil spirit, demon 2 a vicious or wicked person 3 the past 4 any of the five elements, i.e. earth, water, air, fire, ether 5 any living thing
The five elements are called IN pancabuta in Indonesian (see panca=5) and TH เบญจภูต (bentja-put) in Thai, but the word buta in this case does not seem to exist independently, with the meaning of element, besides the compound words here presented. — The lexical relationship between a kind of spirit and the elements might hint at a remote animistic conception, and reminds one of the “elementals” in some Western systems, such as Paracelsus’s.
SK भूत bhuta

IN cakra, cakera (roda): wheel
TH จักร (tjak) (tj-k-r): wheel, discus — จักริน,จักรี (tjakrin, tjakri us. transcribed Chakri): ” one who bears a discus”, a name of the God Vishnu, and the name of the Thai monarch of reigning Chakri dynasty, believed to be an avatar of Vishnu (Longdo dictionary)

TH จัณฑาล (tjantan) (tj-n-t-l): outcast, despised
UR چنڈال (chandal) 1 Hind. lowest caste or a member of this caste; low-born, an outcast 2 miser 3 miscreant
The tchandala, actually ranking below the lowest caste proper (sudra) as well as below all living beings, is defined as the offspring of a woman of the highest caste with a man of the lowest. There must be this specific circumstance: the offspring of a man of the highest caste with a woman of the lowest caste is not so low as the tchandala. — The word has been used by Nietzsche as a surname for the “last man”, i.e. the last of men, namely the Western man.
SK चण्डाल chandala

IN cendana: sandalwood
TH จันทน์ (tjan) (tj-n-t-n): sandalwood
UR چندن (chendan): 1 sandal tree or its wood 2 mark made with red sandal on the forehead — صندل (sandal): same meaning (this last word is Arabic and the obvious origin of the European one; I presume it is itself the Arabic transcription of the Sanskrit; Urdu has thus two words for this object, one Sanskrit and one Arabic from Sanskrit.

UR گج (gaj): elephant — گج پتی (gajapati): “elephants’ master” 1 lord or keeper of elephants 2 a title given to a king — گج موتی (gajamuti): “elephant’s pearl,” fine large pearl supposed to be found in the skull of an elephant (hence a variety of bezoar, besides those supposed to be found in the skulls of snakes and toads according to ancient Western beliefs, and South-Asian beliefs too) (see mote) — گج نال (gajanal): large gun or canon mounted on elephant
There is still another Sanskrit-based correspondence having the meaning of elephant, namely TH หัตถี (hatti) and UR ہاتھی (hathi).

SK काम kama

IN kancana, kencana (emas): gold; fig. money
TH กาญจน์, กาญจนา (ทอง) (kan, kantjana): gold
UR کنچن (kanchan): gold; 2 fig. wealth; money
The main Indonesian word for gold is emas, sometimes written mas. In Thai we find the word มาศ (mat) (m-s), which means both gold and sulphur. There seems to be a correspondence here as well, though I do not know from what spring, because if in Urdu exists the word UR الماس (elmas), rather similar to emas, it is from Arabic and has the sense of diamond. IN Emas/Mas could be the Arabic word still, with some semantic shift, and the Thai similitude either fortuitous or a loan from Arabic as well (indirectly through the Malays).
SK काज्चन kajchana

IN kanta: lens — suryakanta: lens; magnifying glass (see surya)
TH กานต์ (เป๊นที่รัก) (kan) (k-n-t): beloved — จันทรกานต์ (tjantrakan): “moon’s beloved,” i.e. moonstone — สุริยกานต์ (suriyakan): “sun’s beloved,” i.e. burning glass
UR کاچ ؛ کانچ (kanch, kach): glass
My Thai source for “moon’s beloved” and “sun’s beloved” (Longdo) explains the etymology as follows. The moonstone is the moon’s beloved because it attracts the moonbeams, which make it moist. A burning glass is the sun’s beloved because it attracts sunbeams, which make it give fire. In this case TH is not derived from the Sankrit word for glass. An Indonesian Sanskrit-based word for glass is IN kaca, which could well derive from the same origin as UR. However, the etymology of my Thai source for suryakanta seems correct, because of the Indonesian male name Candrakanta (Chandrakanta) which makes sense as “moon’s beloved,” or “half-god beloved” (second meaning of candra in Indonesian), but not so much as “moon glass” or “moon lens”. As “beloved”, in Urdu, is said UR کج (kaj), seemingly we have here an intricate network of interpretations.

SK मण्डल

IN manikam (batu permata; ark. mani): gem, precious stone; archaic. semen
TH มณี (mani): precious stones, gems
UR مانک (manek): jewel; ruby; quartz
As we can see, IN has two meanings (one being archaic): gem and semen. The selfsame meanings are found in the Indonesian word IN jauhar (intan; mani, benih manusia), a term of Arabic origin (جوھر) that exists also in Urdu vocabulary. In both Arabic and Urdu, it has the following meanings: jewel, gem; & essence, matter, substance. The relationships are quite interesting.
