How to add Sata Drives to Dell T410 and bring them Online to raid 5?

Hi again guys thanks for all your input previously.  I'll start again.  Starting with 3 sata I found Sata drive 00 was beyond repair, so I had no OS, raid 5. Repostioning the two remaining satas drives to 00 and 01 i installed esxi 5.5 which is stable, raid 0. Reclaiming 3 other sata drives (now a total o 5 drives) i'd now like to use all drives in a new esxi setup (probably losing the first esxi install), can you advise how to bring the extra 3 drives Online?
i'd like to use raid 5 so if a drive collapses again i don't lose all data in my new esxi build, the drives are all various sizes, 00-150Gb 01-150Gb 03-250Gb 04-80Gb 05-1Tb is this a viable setup?
thanks again all. steve.

Which RAID controller do you have? Depending on what you have it may not even do RAID 5, or at least not well.

RAID usually requires all disks to be the same size.

T410 probably has PERC of some kind and they all do RAID 5; however if you make an array with 2*150GB, 1*250Gb and 1*1TB you will only get 450GB worth of space since the size is defined by the smallest disk.
Keep 03 as a spare for 00 & 01, Lose 04, and buy another 1TB to Mirror with 05
