Look at this particular part, which is causing the first error:
Text1:"{"text
- Minecraft reads
Text:, and is expecting a string (surrounded with quotation marks) to follow
- Minecraft reads
", so starts reading the string to go with Text1 (the key)
- Minecraft reads
{ as the string
- Minecraft reads
", so stops reading the string, and is now expecting a comma to start the next key-value pair, e.g: Text1:"Hello",Text2:"World"
- Minecraft finds
t instead, so throws the unexpected token error
To fix this, you need to escape (put a backslash before) quotation marks that are part of the JSON. \" tells Minecraft to read " just as another character in the string, rather than stopping reading the string, as the " is part of the JSON rather than the top-level NBTData.
Even more confusing is when you have a tellraw command, requiring JSON, within the sign's text JSON. You now need to escape the backslash itself (\\) before the quotation mark (\") so that it's not read as NBTData, nor as the sign's text JSON, but as part of a string within the sign's text JSON.
Fully fixed command:
/give @p sign 1 0 {BlockEntityTag:{Text1:"{\"text\":\"[MF2]\",\"color\":\"gold\",\"clickEvent\":{\"action\":\"run_command\",\"value\":\"tellraw @a [{\\\"text\\\":\\\"[MF2] \\\",\\\"color\\\":\\\"gold\\\"},{\\\"selector\\\":\\\"@p\\\",\\\"color\\\":\\\"dark_aqua\\\"},{\\\"text\\\":\\\" is now an admin of the server!\\\",\\\"color\\\":\\\"white\\\"}]\"}}",Text3:"{\"text\":\"Click to join Admin\",\"color\":\"dark_aqua\",\"clickEvent\":{\"action\":\"run_command\",\"value\":\"scoreboard teams join admin @p\"}}"},display:{Name:"Custom Sign"}}
In the future, use a generator, or use a trigger/scoreboard command to set off the tellraw command, as this can get pretty confusing and annoying to find errors in.
Do this for all of your armor stands. I believe this is the only way for it to work. It is going to be more command blocks, but I think its the only working one.
/execute @e[type=ArmorStand,name=(insertname)] ~ ~ ~ tellraw @a[score_goto=-1]
{
"selector": "@e[type=ArmorStand,r=1]",
"clickEvent": {
"action": "run_command",
"value": "/tp @p @e[type=ArmorStand,name=(insertname)]"
},
"color":"blue"
}

To clarify Daniel's answer, you can assign a tag to a player when they click on a command in the chat using the following command in a tellraw command:
Then, in a repeating command block chain, you can execute the following 3 commands in order:
