Hi Tricia,
I think you have come to the right website to ask about Israeli Music, If you will also check out this website A bit more deeper you will get A more clear idea about the Israeli Music and its artists, now regarding the questions you have asked.
1 & 2.Just like Chosen has written I prefer not to write personal id on the web.
3.There are many artists that are popular among this age group, there isnt one single artist that stands above the rest, I also think that Chosen has covered most of the current popular singers.
4. The most popular gerne is probably Oriental, the music of this gerne is usually Happy music, music that is played A lot at weddings, bar mitzvahs, private parties etc. Pop and Rock music and also Hip Hop are not far behind.
5. I don't go A lot to concerts but there are many Free Concerts in Israel, especially concerts that are aranged by City Halls of each town. next week is Pesach after the last day of Pesach my Home Town has already organized A concert with Eyal Golan And Lior Narkis, the concert is like most of the concerts, free!!
next month you also have the israeli 60th Independence Day and every year you have tons of concerts with all of the Israeli artists all over the country.
6. I guess so, as Pop, Rock etc music is all main stream nowdays.
7. Like I mentioned above, most gernes nowdays are main stream.
8. American artists are very popular in Israel, they are more popular than even many of the western country, you should also remember that Isarel is A western country with all that goes with it, including tons of music channels on the tv (all the mtv channels), and tons of radio stataions.
9. There are many music festivals in Israel, also like Chosen mentioned, many are organized by the city halls. these music festivals take place usually in the Summer or at special occasions, for example the soon coming Independence Day, A day at which you can see all of your favorite artists performing.
10. Like most countries in the world there are various types of clubs/pub's/bar's/disco's, different with different themes that play the music style they are built on, so you can find clubs/bar's with each and every kind/style/gerne of music, all depends in what you like, we have it all!!
Wishing you and everyone at Kikar-Israel A lovely weekend
