o well.....my experience are not that deep..but..i will try to help you
鍾意 : you will probably think of him sometimes..you want him to notice you..you want to have some touch with him..whatever hug..hold hand..just a little touch.....you want to talk to him.. but you will probably still have some other people in your mind..
好感 :well....he is probably better and the one that you will notice and interesting in in a group of people...but you just think he is good-looking so you like him better..or he is nice...so you have好感...
愛 - you love him...so you don't care whatever he is doing..and you can do everthing for him and no complain..sometimes you don't even want to force him to love you...if he is happy...you are happy...you don't want to hurt him...if you love somebody...you almost forget about think of yourself.
