An admin is a administrator of a Minecraft Server. They are of a higher rank than Moderators.
could be that minecraft updated and your server is out of date. if you are using a bukkit server than check your craftbukkit and make sure the number that follows it equals your minecraft version. Your question doesnt give a lot of detail though so thats the first problem i would check, if you have more details (like an error or something) post it in the Discussion and we will figure it out.
It means the server is using an old version, older than the version you are using.
If you want to play Minecraft on a different version than the most recent, then you will need to look online for a Minecraft server list and make sure to include the version number that you are trying to play on.
It means the server is iether down,reloading or the server creator hasn't port forwarded the server It means that the set timeout time in the java code of minecraft is less time than it took to connect to the server meaning the connection has 'timed out' this is because the server has been unresponsive for more then said amount of time.
They are the admins of the server. They can kick, ban, mute, change the time of day, switch from creative to survival or survival to creative, and have more control over the server than regular users.
It depends. If you are using a public computer, it will be a monthly fee. If you use anything other than a public computer, it is free. A better explanation can be found on Minecraft Wiki.
if its ur server than try restarting it but if its a friends server than wait a bit
It usually means the server version is older then your game version. Every time Minecraft updates they usually update the server also.
The spawn area in a server is protected. (A radius of 33 blocks). Have them move more than 33 blocks away from the spawn point, and then they will be able to build.
