Is there anyone available to help me to learn animation?
Why not google animation lessons? You can get animation courses and stuff free and paid. If you want to learn the basics, you can easily find YouTube tutorials showing you how to get the basics down. I’m an amateur animator, but I’m pretty much teaching myself. Once you get the hang of keeping track of objects and keyframes, and learn what interpolation modes do, and learn how to use the graph, it gets easier and easier.
