Check your terminology. Do you mean 3 phase (3 hot wires, a neutral wire, and a ground wire) power that would be used in a commercial building? If so, yes they are made. Most of the ones I've seen (I've only really looked on eBay) were large, expensive models designed so suppost an enormous load just long wnough for a generator to start. You can probably find ones designed for longer run times, though.
There has no 5-phase power supply available in the market.
Uninterruptible power supplies (UPS) typically use sealed lead-acid batteries, although some models may also use lithium-ion batteries. These batteries provide backup power to the UPS when there is an interruption in the main power source, allowing for continuity of power supply to connected devices.
A uninterruptible power supply (UPS) is a system that will store a certain amount of power when you feed power into it while providing power to connected appliances. When it experiences a outage, it will provide power to the same appliances through its previously-stored power for a certain amount of time without much of a delay in switching power sources, thus the term.
If there is not enough power and the power trips, your appliances will lose power abruptly. This sudden loss of power can cause damage to sensitive electronics and appliances, particularly if the power surges when it returns. It is recommended to use surge protectors and Uninterruptible Power Supply (UPS) devices to protect your appliances in such situations.
Emergency power equipment in a building typically includes generators, backup batteries, and uninterruptible power supply (UPS) systems. These systems provide electricity in the event of a power outage to ensure that critical systems and equipment continue to operate. Regular maintenance and testing of these emergency power systems are essential to ensure their reliability in emergency situations.
When purchasing a UPS (Uninterruptible Power Supply), you need to match the power needs of your system according to the unit of measure called volt-amperes or VA. This ensures that the UPS can support the power requirements of your equipment and provide sufficient backup power during outages.

As long as the UPS has power. UPS's have different run times.

Give you time to shut down if you lose your power. Not a replacement for regular back-ups though.
