I know how to specify trackers in the magnet URL scheme. I need to use &tr=[tracker address]. But when I add it, all the specified trackers in the magnet link go into Tier-0. What should I do if I want to add 2 trackers in Tier-0 and then another 2 trackers in Tier-1?

Trackers are placed in groups, or tiers, with a tracker randomly chosen from the top tier and tried, moving to the next tier if all the trackers in the top tier fail.

If you need more information about Tiers: Multitracker on Wikipedia

Eg: The following magnet-URI is the magnet URI of Ubuntu ISO and when I add this into a torrent client, all specified trackers go into Tier-0. I know that I can select a tracker and click "Down" to move it to the next Tier(ie, Tier-1) but is there any way to specify these Tiers within the magnet URI itself?

magnet:?xt=urn:btih:D0F23C109D8662A3FE9338F75839AF8D57E5D4A9 &dn=Ubuntu+MATE+16.04.2+%5BMATE%5D%5Barmhf%5D%5Bimg.xz%5D%5BUzerus%5D &tr=udp%3A%2F%2Ftracker.openbittorrent.com%3A80%2Fannounce &tr=udp%3A%2F%2Ftracker.zer0day.to%3A1337%2Fannounce &tr=udp%3A%2F%2Ftracker.leechers-paradise.org%3A6969%2Fannounce &tr=udp%3A%2F%2Fcoppersurfer.tk%3A6969%2Fannounce

No, there is no way to specify in a magnet link, what tier a tracker is added to.

There is nothing in the BitTorrent protocol specification on how to do that.
So it's up to the implementer of a client to decide how to do it.

Deluge, as you have noticed, adds all trackers to tier-0.
Other clients, for example: µtorrent, adds every tracker in it's own, separate tier.
