In short, yes, it is entirely possible to kill all 6 barrow's brothers with melee at your level. Would it be recommended? No. When I made my first trip to the Barrows (c2006), I was similar to your level and managed to melee all 6 brothers. It was terribly inefficient, even for my level. I used the below setup, but you have considerably better options. Regarding funding issues, I would suggest selling your dragon boots for rune, as that would save you a considerable amount of money (~160k) for a drop of just +2 strength. You will need to pray against all 6 brothers. It will take you a long time to kill each brother, and will require several prayer pots. Should you decide to melee, it would be in your best interest to obtain a dragon weapon (preferably scimitar, but longsword would also work). For melee you will also want to bring a pure set (super attack + strength). Bring a spec weapon (you mentioned you have a dds) and wear prayer/strength boosting armor. I would recommend a prayer pot per brother, you may need more. You will also want a high healing food (monkfish/shark) filling the rest of your inventory. The order you kill the brothers is irrelevant, just be sure to prayer the appropriate protection prayer. Verac will be the hardest to kill, as he will hit through prayer. If instead you choose to mage, you would want to wear at a minimum mystic top and bottom while casting water blast. Mage the four melee brothers (dharok, verac, guthan, torag) and the ranged brother (karil). Bring a melee primary + spec weapon to kill the mage brother (ahrim). Prayer needs may be higher than above, I honestly don't know how much prayer you will consume. Fill the rest of your inventory with high healing food. You may find it useful to bring rune plate + legs to switch to in the tunnels. Be sure to bring a spade and a 1 click tele regardless. You may also find it useful to wear a ring of life. Again, killing the brothers at your level will take a considerable amount of time and will not likely provide any meaningful reward. That said, it is fun and good luck with your future bossing.
