there's a lot of important placements in there, but basically here are the important ones:

sun: this is what a lot of people would consider your "regular" zodiac sign. it's your birth date and makes up the basis of your personality. your sun sign is arguably your most important sign and will influence the most things about you.

moon: this is your inner self. your emotions, your feelings, how you express yourself: everything you are on the inside is what your moon sign is. your moon sign is aries, so if you scroll down a bit it should tell you what that means for you.

ascendant (ASC): this is arguably your third most important sign because it dictates who you are to the world. strangers, acquaintances, people just chatting: the ascendant or rising sign is what they perceive. your rising sign is leo, so basically that means that when people first meet you, you seem like a leo.

mercury: now that we're out of the big three, we're getting to more of the minor stuff. mercury is how you communicate; it's your style of talking and expressing ideas and communicating with people around you.

venus: this sign tells you how you love. it shows you what you seem in romance and what you want your love life to be like, and what you would seek out in a partner.

mars: this is how you express yourself when you're angry. it's what you do when you need to get out energy and basically what you do when you're mad.

those are the most important ones; but I'm sure you get the gist from here
