Regular Union Army

Many of the men in these units may have been so-called "galvanized Yankees" who originally served on the Confederate side, and took an oath of allegiance to the Union to avoid confinement as a prisoner of war.

U.S. Coastal Artillery Batteries
I haven't been able to find anything about these units. They're not included in Volume 3 of Dyer's Compendium. The references below are taken from National Archives Microfilm Series T-288 General Index to Pension Files 1861 - 1934.

Union Army Volunteers from the States

Indiana, Iowa, Kentucky, Maine, North Carolina, Tennessee.

Indiana
National Archives microfilm series M-540 is the index to compiled service records of volunteers from Indiana. You can find rosters of all of the Indiana regiments in a set of books called "Report of the Adjutant General of the State of Indiana". Regimental histories and more for all units can be found at a web site for Indiana in the Civil War.

6th Indiana Cavalry.

6th Indiana Infantry. 7th Indiana Infantry. 9th Indiana Cavalry. AKA 121st Regiment Indiana Volunteers. Regimental roster on LDS film #1,703,855.

13th Indiana Infantry. Regimental roster on LDS film #1,703,856.

The regiment was mustered in at Indianapolis June 19, 1861, under the command of Col. Sullivan, and sent to West Virginia July 4, where it joined the brigade of Brig. Gen. W. S. Rosecrans. On the morning of July 11 Gen. Rosecrans led his brigade of about 1900 men through a trackless forest around to the rear of the Confederate position of perhaps 800 to 1200 men astride the Buckhannon-Beverly Road atop Rich Mountain, in Randolph County, Virginia. Reaching the road around 2 PM, they advanced along it over the crest of the hill. The 13th was supposed to send three companies to skirmish down the hill and three more companies to cover a small valley on the left, but Col. Sullivan misunderstood the order and took the whole regiment up the hill. After 40 minutes it was repositioned, Major Foster of the 13th later being complimented for his coolness in forming a portion of his men while under fire from two enemy cannons. Col. Sullivan with four companies was to charge around the road on the left. When the four regiments were set for the attack, the 19th Ohio formed into line and poured two volleys into the enemy force, which broke and retreated. The 8th and 10th Indiana charged along the road. Gen. Rosecrans himself encouraged the 13th's charge as the rebels were dispersing, capturing several prisoners. The battle was soon over, with many Confederate casualties, and 21 prisoners, two cannons, and all of the supply train captured. Rosecrans' brigade lost 12 men killed and 49 wounded.(1)
