Tamarind with a 'd' correct? There is actually a thread here on SMF about using tamarind in soap:
https://www.soapmakingforum.com/threads/cp-soap-adding-plant-extracts-tamarind.36718/
Most of the people in that thread are no longer posting here, but you can at least read about the soapmaker's experience by reading that thread.
As for what recipe to use with the given oils you currently have, I am pretty sure you will get a few replies.
I'd go with something like 70% Olive Oil, 10% Red Palm Oil, 15% Palm Kernal Oil, 5% Castor. I'd soap at only 2% SuperFat, because Tamarind is oily by itself and adds to the SF of the soap. And I'd probably use a 33% Lye Concentration rather than using the default setting in the
lye calculator. I don't like the color that too much red palm oil gives the soap, so that's why only 10%, and it can stain your soap molds if they are silicone. It also can produce orange colored soap lather when used at high percentages. I also prefer a low cleansing number because it's kinder to my skin type, but there are many people who are fine with higher cleansing numbers (cleansing = stripping oils from the skin), and if you are young that might be the case for you as well. In which case, you could reduce the OO and increase the Palm Kernal Oil a by perhaps 10%.
With high OO in the soap, though, it's going to need a bit longer cure than it would with a lower percentage, so that's also a consideration. So I also have to ask what other oils are available to you? Sometimes there are better oils for soap than what we have on hand, but we don't realize how much better they might be until we ask. For example, can you get palm oil that is not red, and can you get cocoa butter or even coconut oil, for example. A list of any others you could easily manage to purchase would be helpful.
Others with more experience than I will surely come along and give you some advice on putting together a recipe with the oils you have on hand.
Here is a video of a soapmaker making tamarind soap:
ETA: For any new soap recipe, I highly recommend making a small batch size. 500 grams total batch size is a good starting point for a beginner, in my opinion.
