How can I achieve material like the one in the castle? It looks like glitters, Sequin, led dots. I don't know to be exact.
Also, I want to make subtle animation on it like random shine over time

It should be descriptive but succinct, unique and identifying, summarizing the issue in such way that anyone searching for a similar problem may easily find it. Use the edit link above, remove anything superfluous, avoid words like "this","issue with" or "question about". Remember, your title is the first thing potential visitors will see, answers you get depend heavily on how inviting it is.

Try something like this - if you are using EEVEE, remember to change the Blend Mode to Alpha Blend (Right side). Backface culling and/or Show Backface are optional - I showed an example with backface cullling off and on - it may require a bit of tweaking of the colorramp with it off, because there are double the amount of "flakes". Also, if using eevee, don't forget to enable "Bloom" to get the glow effect. If you are using Cycles, you will have to add the glow afterwards in the compositior with a Glare Node.
Show Backface off
Show Backface on
If you want to animate it, there are 2 ways I can think of. First, if you want the "glitter " itself to move, you can use the setup below, either using the mapping node to move the glitter "downwards", or by using a 4D Voronoi texture and animating the W, or both. Either way, the movement is driven by a Value node, with #frame written in the value box (to make the value equal to the current frame at all times).
The second way, is to change the brightness of each piece of glitter, by "dragging" a noise texture across it, making random areas brighter and dimmer as it passes. Value node works the same way as the above example.
