My life problems

I have a group of 4 friends in which 2 friends keep telling me i have a lot of money and keep asking for some as a joke so i am irritated so should i tell them to stop these 2 friends also hide a lot of things from me and my bestie and don’t talk with us much rather they talk with their new friend they also keep telling me that i am topper and once we had a test where they scored 5 out of 5 in test by cheating also i scored 4 out 5 in the same test as I didn’t come prepared they still keep telling me that they scored more than me but ik they did by cheating and if i tell me then they say u are so annoying it doesn’t matter blah blah are they toxic ??should i tell them to stop??
